• WELL MADE: Replace leaking valve cores in charged HVAC/refrigeration systems without releasing harmful refrigerants (R22, R32, R410A, R134a, R407, R404). Built-in shut-off ball valve and airtight O-ring seal prevent leaks, eliminating the need for refrigerant recovery or recharging—saves time, reduces waste, and complies with environmental standards.
• Dual-Size Universal Compatibility (1/4" & 5/16" SAE Ports): Perfectly fits most residential/commercial AC systems, mini-split systems, and home refrigeration equipment. Includes a brass R410A/R32 adapter (1/4" male SAE to 5/16" female SAE) for seamless compatibility with all major refrigerant types. Note: Not suitable for automotive AC systems.
• Pro-Grade Durability & Anti-Slip Ergonomics: Crafted from heavy-duty solid brass and CNC-machined aviation aluminum—resists high pressure, corrosion, and chemical damage. Anti-slip knurled grip ensures a secure hold even with gloves, while the magnetic core grabber safely retrieves stuck valve cores. 3X longer lifespan than plastic tools, built for repeated professional use.
• 5-Minute DIY Installation (No Expertise Needed): External bypass port and reverse-thread design simplify valve core removal/installation—no special tools or technical skills required. A quarter-turn ball valve handle enables quick operation, and the integrated core grabber easily locks onto valve cores for precise control. Ideal for HVAC technicians and DIY enthusiasts alike.
• Package Included: 1* Valve Core Remover, 1 *R410 R32 Brass Adapter, 10* Valve Cores, 5* brass nuts.
